Claim This BusinessFoster Mechanical Inc has operated as a licensed air conditioning contractor in Phoenix since 1992, holding ROC101124 and ROC123666 credentials. The company maintains a 4.9-star average across 23 customer reviews, reflecting decades of service to residents throughout the Valley including the North Central Corridor and surrounding neighborhoods near their 5th Avenue location. Their physical presence at 9224 N 5th Ave places them centrally for both routine maintenance calls and emergency cooling repairs across the metropolitan area.
This contractor distinguishes itself as a Lennox dealer with demonstrated warranty resolution capabilities, having successfully navigated manufacturer warranty claims on behalf of homeowners. Their Phoenix operation runs Monday through Friday from 7:30 AM to 5 PM, scheduling same-day service for urgent calls during extreme heat events when air conditioning failure poses genuine health risks. The combination of licensed, bonded, and insured status provides residential clients peace of mind when inviting technicians into their homes.
Reviewers consistently name two team members: Justin, the lead technician praised for diagnostic accuracy and fair pricing on repairs including new AC coil installation and furnace troubleshooting; and Shannon in the office, credited for warranty advocacy and scheduling flexibility. One reviewer describes Shannon spending hours on the phone with Lennox to resolve a warranty glitch before Justin arrived the same day to complete the installation. Several customers specifically note choosing Foster Mechanical for 15 to 20 years rather than risk unfamiliar contractors.
The 4.9-star average across 23 reviews reflects overwhelmingly positive sentiment. Five reviewers explicitly name either Justin or Shannon as the technician or office contact handling their service, while another reviewer highlights a same-day response during an urgent call. The only recurring theme in feedback relates to pricing, balanced against consistent praise for diagnostic accuracy and honest assessments.
